WARNING! To reduce the risk of personal injury, adjust the volume before putting on headphones,

Environmental Notices.
To connect external devices such as external speakers, headphones, or a microphone, refer to the
information provided with the device. For best results, remember the following tips:
●
Be sure that the device cable is securely connected to the correct jack on your computer. (Cable
connectors are normally color-coded to match the corresponding jacks on the computer.)

programs that use the device.
